In this section, we will focus on listing all the courses in the database on the page. We will begin by adding the get action to our Courses controller that will use the getCourses method provided by the courses model. Once the data is retrieved from the getCourses method, the data is forwarded to the get.php view from our get action in the controllers/courses.php file:

public function get($id=null){
  $this->view->course_data = $this->model->getCourses();
  $this->view->render('courses/get');
}

The code of the models/courses_model.php file is as follows:

public function getCourses(){
  return $this->db->query("SELECT course_id, name, description FROM courses;")->fetchAll(PDO::FETCH_ASSOC);
}

The code of the views/courses/get.php file is as follows:

<div id="getCourses">
  <table>
    <tr>
      <th>Course Id</th>
      <th>Course Name</th>
      <th>Description</th>
    </tr>
    <?php...
